Description
Technical field
The present invention relates to field of automobile, especially a kind of friction material for making automobile brake lining plate and
Preparation method.
Background technique
In daily life, we are often it can be found that in humidity or have a small amount of water between the contact surface of two opposite slidings
It is bigger than frictional force under conditions of being completely dried under conditions of point, such as: go friction glass that can feel when our hand is very dry
Smoother is obtained, goes friction glass that can feel very jerky when hand is perspired or has a small amount of moisture.In automotive brake, especially
There is also this phenomenons in the braking process of drum brake, in general, the vehicle using drum brake is travelled in dry pavement
When can normal retarding braking, once travelled in the rainy day, the case where wheel lock up when being easy for braking, vehicle whipping.Invention
People by for a long time observe and the study found that when vehicle under conditions of splashing on rainy day or road surface slippery situation, water when driving, brake
It has a small amount of moisture between brake lining and brake drum to immerse but will not be completely sunk in the water, at this point, brake lining is in
State semi-moist immerses a small amount of moisture between the hole of friction material but is unlikely to form moisture film between rubbing surface, due to portion
Point friction material softens so that the coefficient of friction of friction material becomes larger, the rubbing surface of brake when eventually leading to vehicle braking
Between frictional force become larger suddenly, braking moment increases extremely, and wheel shifts to an earlier date locking, gently then generates whipping, heavy then cause to overturn
Accident seriously jeopardizes driver and passenger's safety.
